Solution
Hydrogen peroxide can be obtained by the auto-oxidation of 2-ethyl anthraquinol.
2-Ethylanthraquinol ⇌ oxidized product + H2O2
The reduced product is dissolved in a mixture of benzene and cyclohexanol and when air is passed through this, it is oxidised back to 2-Ethylanthraquinone and hydrogen peroxide is also produced along with.
This process is very cheap because 2-Ethylanthraquinone can be used again and again.
